A lobectomy of the thyroid gland A total thyroidectomy. Hemithyroidectomy — Entire isthmus is removed along with 1 lobe. Done in benign diseases of only 1 lobe. Subtotal thyroidectomy — Removal of majority of both lobes leaving behind 4-5 grams (equivalent to the size of a normal thyroid gland) of thyroid tissue on one or both sides—this used to be the most common operation for ...
Operations involve removal of the thyroid gland (thyroidectomy) either as a part of the gland (lobectomy or hemithyroidectomy), or the whole gland (total thyroidectomy). Incomplete resections (sub-total or near total thyroidectomy) are also infrequently performed, but are disfavored by most surgeons [citation needed].
A large majority of the thyroid may be removed (subtotal thyroidectomy) to treat the hyperthyroidism of Graves' disease, or to remove a goiter that is unsightly or impinges on vital structures. [citation needed] A complete thyroidectomy of the entire thyroid, including associated lymph nodes, is the preferred treatment for thyroid cancer.
Post-operative complications at high-volume thyroid surgery centers with experienced surgeons are comparable to that of hemithyroidectomy. Arguments for hemithyroidectomy: Most patients have low-risk cancer with an excellent prognosis, with similar survival outcomes in low-risk patients who undergo total thyroidectomy versus hemithyroidectomy.
For patients with benign thyroid adenomata, thyroid lobectomy and isthmusectomy is a sufficient surgical treatment. This procedure is also adequate for patients with minimally invasive thyroid cancer. When histological examination shows no signs of malignancy, then no further intervention is required.
Parathyroidectomy is the surgical removal of one or more of the (usually) four parathyroid glands.This procedure is used to remove an adenoma or hyperplasia of these glands when they are producing excessive parathyroid hormone (PTH): hyperparathyroidism.
A lobectomy of the lung is performed in early-stage non-small cell lung cancer patients. [2] [3] It is not performed on patients that have lung cancer that has spread to other parts of the body. Tumor size, type, and location are major factors as to whether a lobectomy is performed. This can be due to cancer or smoking.
If the nodule is malignant or has indeterminate cytologic features, it may require surgery. [2] A thyroidectomy is a medium-risk surgery that can result in complications if not performed correctly. Problems with the voice, nerve or muscular damage, or bleeding from a lacerated blood vessel are rare but serious complications that may occur.
